WALTER D. YOUNG, OF BALTIMORE, MARYLAND, ASSIGNOR TO NATIONAL SAFETY THIRD RAIL COMPANY, OF NEW YORK, N. Y.

RAIL-CHAIR AND INSULATOR.

SPECIFICATION forming part Of Letters'Patent NO. 715,329, dated December 9, 1902. Application filed October 18, 1901. Serial No- 79, l19. (N model.)

To ctZZ whom, it may concern:

Be it known that I, WALTER D. YOUNG, residing at Baltimore city, State of Maryland, have invented a new and Improved Rail- Chair and Insulator, of which the following is a specification.

This invention is in the nature of a combined rail-chair and insulator for third-rail electric-railway systems, adapted to efiect- IO ively serve for rigidly clamping the third or conductor rail sections in position and insulate the same from the contiguous rails and metal work and also serve for holding the guard members in their proper position alongr5 side the third rail.

In its generic nature my invention comprehends a third-rail insulator having a base portion provided with means for supporting a guard-plank, and in its more subordinate features it embodies certain details of construction and peculiar and novel arrangement of parts, all of which will hereinafter be fully described, and particularly pointed out in the appended claims, reference being bad to the accompanying drawings, in which Figure l is an end elevation of my improved combined insulator and rail-chair, the guardrails being shown in transverse section. Fig. 2 is a cross-section of the same on the line 3 3o 3 of Fig. 1. Fig. 3 is a plan view of the insulator rail-chair and guard-plank-supporting means, the third or conductor rail being in dotted lines and the guard-rails being omitted.

In the practical construction of my invention the same comprises a casting 1, having a flat base portion 1 whoseopposite longitudinal ends terminate in ears 1", bent down at an angle to engage suitable depressions b 40 in the cross-tie B, on which the said casting is securely held by the spikes A A, that pass through the ears 1 as shown. The member 1 is also formed with two parallel longitudi- Bally-extending inwardly-inclined flanges 1,

that extend the full length thereof, and said flanges are integrally joined with the base portion 1 of the oppositely-disposed vertically-extending bracket-arms or standards I which have flanges 1 1 to receive the guardplanks C, the lower ends of which rest on the presently appear.

base-flanges 1 and the bodies of which are made fast to the flanges 1 by the bolts and nuts 2 2, and said planks O extend up in a plane above the contact-surface of the third or contact rail R, the reason for which will The standards or brackets 1 have strengthening ribs or flanges, as clearly shown in the drawings.

D designates an insulator-block which has its base made dovetailed in longitudinal direction, whereby said base may be conveniently slid endwise into position between the inclined flanges 1 of the base 1, it being held from endwise movement beyond one end of the base 1 by the stop-flange l, as best shown in Fig. 3. The insulator-block D, which is of granite or other suitable material, is of substantially square shape in plan view, and its upper end terminates in vertical extension (1, adapted to fit the socket e in the under side of the metal chair or capplate E, which rests upon the portion 61 of the insulator-block and may be made fast thereto by lead coating or any other suitable cementing material. The upper surface of the chair E is flat to receive the base of the rail R, and said upper surface at diametricaliy opposite corners has claws e e to fit over and clamp the flanges a a of the rail A, as clearly shown in Fig. 1.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the operation and advantages of my invention will be readily understood.

In assembling the several parts for use the base or casting 1 is spiked at one end to the tie, after which the insulator-block D is slid endwise between the flanges 1 1 of the member 1 until its inner end engages the stopflange 1 after which the spike is driven to secure the other end of the casting 1 and as the head of the spike is in a plane above the bottom of the insulator-block it follows said block cannot work out from between the flanges 1 1 at that end. After the block D is properly fitted the socketed chair E is fitted upon the insulator-block and made fast in any suitable manner, after which the rail R is seated on the chair E and made to interlock with the claws e. The guard-planks O are then secured in position, and the upper 10o ends being above the top of the conductorrail a protecting-trough for the conductorrail is provided and danger of accident by contact with any section of the rail that may be alive is reduced to the minimum.

Having thus described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. Athird-rail insulator, comprising a base having outwardly and downwardly extending spike receiving sections, and parallel inwardlyinclined flanges, and an insulatorblock having its base formed to slidably enter between said flanges, for the purposes set forth.

2. The combination with the base 1, having parallel flanges 1 1, inclined inwardly, spikeears at the opposite ends, and a stop-flange 1 cooperating with flanges 1, and an insulator-block having a dovetailed base to slide WALTER D. YOUNG.
